Devon Energy Corp. has named David Harris as executive vice president of exploration and production as Tony Vaughn prepares to retire, the company said in a news release Sept. 16.

Having served in numerous leadership positions with increasing responsibility, Harris was most recently senior vice president of E&P, where he was responsible for the company’s business development and various operating functions, Devon said.

“This transition has been carefully planned and David is a seasoned and trusted leader at Devon who consistently delivers results,” Devon Energy CEO Dave Hager said in the release. “His decisive leadership and deep experiences across the entire value chain of our business uniquely qualify him for this role.”

Vaughn, who will retire after 20 years of service, will serve as special advisor through May 2020.

“His legacy of integrity and humility, coupled with top-tier operational capabilities, has helped us build a strong foundation for future success,” Hager said of Vaughn.
